Trackback "response" not used consistently

[NathanWong]

As you're probably aware, wp_trackback.php has a function called trackback_response() that sends an error (or says "no errors found" at the end). This works great, except for one problem. When there's an error from within wp_new_comment (for example "Sorry, you can only post a new comment once every 15 seconds. Slow down cowboy." and "Duplicate comment detected; it looks as though you've already said that!"), it shows the textual error, and doesn't respond any XML content (not to mention forcing the page to be non-XML compliant).

While I realize this is a minor detail, and it would take a much more advanced error system to overcome, I thought I'd report it anyway.

No one bit in a year. Closing for now.

This can mess up trackbacks completely, so re-opening it. Not life-threatening, but not that insignificant.

Options are to add a "silent mode" to wp_insert_comment() or change wp_insert_comment() to return a WP_Error instead, and let the caller decide what to do with the result.

#3775 has a similar problem, with wp_die() die()ing with values that don't work with AJAX responses.

With a wee bit 'o' output buffering, I think the problem's licked.

Never mind, patch doesn't fix.

Reclosing as wontfix as this ticket has once again gone to sleep.

Feel free to re-open if you have additional patches/information/suggestions/...
